ALEXANDER J. POLLOOK, OF ST. LOUIS, MISSOURI.

JEWELRY-CLASP.

T 0 aZZ whom it may concern:

Be it known that I, ALEXANDER J. POL- LOOK, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented a certain new and useful Improvement in Jewelry-Clasps, of which the following is a specification, reference being had to the accompanying drawings, forming a part of this specification, in which Figure 1 is a side elevational view of my new clasp, showing the parts of the same connected or joined together; Fig. 2 is a similar view, showing the parts detached or disconnected and in a position at right angles to the position shown in Fig. 1; and Fig. 3 is a longitudinal sectional view of the socket member.

This invention relates to a certain new and useful improvement in jewelry clasps.

The object of my invention is to provide a jewelry clasp which is strong, not easily broken, and one in which the socket and catch members are held securely together and in which said socket and catch members will not become disengaged by slight or accidental pressure on the catch member.

Nith this object in view, my invention consists in the novel construction, arrange ment, and combination of the several parts, all as will hereinafter be described and pointed out in the claims.

In the drawings, 1 indicates the socket member, which is preferably of cylindrical form. This socket member 1 is preferably closed at one end and provided with a loop or eye 2, to which is designed to be attached one end of a necklace or chain, said socket member being adapted to receive in its other end a catch member 3, which is made to fit the interior of socket 1 and is provided with a corresponding loop or eye 4:, to which the other end of said necklace or chain is designed to be attached. Catch member 3, as shown in the drawings, comprises a body portion and a pair of oppositely-disposed resilient prong-members 5 extending from the sides of said body portion, between which prong-members 5 and also extending from said body portion is a middle or pull portion 13, at the end of which may be formed said ring or eye 1. The said body portion of said catch member 3 is adapted to firmly and snugly fit within, and to slidingly abut against the sides whereby lateral of, said socket member 1, movement of the catch Specification of Letters Patent.

member within said socket member is prevented, the outer contour of said body portion preferably corresponding with the inner contour of the socket member. The outer end of prongs 5 are formed with heads 6, which are notched or grooved, as at 7, to provide a grasping portion to facilitate the removal of the catch member from the socket member. Said prongs 5 are also provided with notches 8 adjacent the heads 6, which are adapted to receive a flange or ring 9 formed on the outer end of the socket member. This ring or flange 9 is preferably formed by cutting away the walls of the socket member on opposite sides thereof, as at 10, see particularly Figs. 2 and 3. The prongs 5 are also provided with outwardly flaring or beveled portions 11, which ride under the ring 9 of the socket when the socket and catch members are being joined, so as to force the prongs 5 inwardly until notches S therein register with said ring 9, at which time said beveled portions 11 will pass into open portions 10 of the socket member, when the catch member will snap into locked position and is firmly held.

The catch member 3 may be conveniently made of one piece of any suitable metal. The outer contour thereof with the notches S and beveled portions or shoulders 11 and heads 6 can be readily formed on a lathe, and the prongs 5 formed by slitting or sawcutting the catch member endwise a suiticient distance, as at 12, leaving the cylindrical )ortion 3, and by making two cuts the mic dle or pull portion 13 is provided, at the end of which is ring 4. In this way a pull central or axial to the clasp is provided, thereby avoiding any tendency to strain or break the catch member.

To remove the catch member 3 from the socket member 1, the prongs 5 are pressed. together, the nails of the person using the clasp entering the notches 7, which releases the ring 9 from engagement with the groove 8 and allows the beveled portions or shoulders 11 to become disengaged from open portions 10.

The beveled portions 11 entering the open portions 10 of the socket member and the ring 9 of the socket member registering with or entering the groove 8 of the catch member form a strong and positive connection between said socket and catch members, and said catch member cannot be released from engagement with said socket member except by considerable pressure applied directly on the prongs 5 pressing the same together.

I have found my clasp to be strong, easy and chea to manufacture, and one which fully perf drms the object heretofore stated. I am also aware that minor changes in the form and construction of my clasp may be made and substituted for those herein shown and described without in the least departing from the nature and spirit of my invention, as defined by the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. A jewelry=clasp or the like comprising a socket-member having a chain-attaching member at one end thereof and cut-out portions in its wall near the other end thereof, and a catch-member adapted to removably fit within said socket member and consisting of a body-portion, resilient prong-members extending from said body portion, and a notch and shoulder on each of said prongmembers adapted to cooperate with one end of said socket-member and with said cut-out portions in its Wall to lock said socket and catch-members together, the outer end of said prong-members being adapted to extend beyond the body of said socket-member when said socket and catch-members are locked together; substantially as described.

2. A jewelry clasp comprising a socket member having cut-away portions in its walls and a ring on one end thereof, and a catch member consisting of a body portion fitting within said socket member, oppositely-disposed resilient rongs on said body portion, shoulders on said prongs adapted to enter said cut-away portions in said socket member, and a groove on said rongs adapted to receive said ring when tiie socket and catch members are joined together, substantially as described.

3. In a jewelry clasp, the combination with a socket member to which one end of a chain is designed to be attached, said socket member having cut-away portions in its walls and a ring on one end thereof, of a catch member having a body portion adapted to fit within said socket member, oppositely disposed resilient prong members extending from said body portion, a central pull portion extending from said body portion between said prong members and to which the other end of said chain is designed to be attached, and a groove and shoulders on said prong members adapted to cooperate with said cut-away portions and said ring of said socket member to lock said catch and socket members together; substantially as described.

4. A jewelry-clasp or the like comprising a socket-member having a chain-attaching member at one end thereof and cut-out portions in its wall near the other end thereof, and a catch-member adapted to slidingly fit in said socket-member and consisting of a body portion having an outer contour corresponding to the inner contour of said socket-member, oppositely-disposed resilient prong-members extending from said bodyportion, a notch and shoulder on each of said prong-members adapted to cooperate with one end of said socket-member and with said cut-out portions in its wall to lock said socket and catch-members together, and a pull-portion extending from said body portion between said prong-members and to which pull-portion the other end of said chain is adapted to be attached, the outer ends of said prong-members and pull-portion being adapted to extend beyond the body of said socket-member when said socket and catch-members are locked together substantially as described.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
